To all whom it may concern:

Be it known that I, RANDOLPH CRoMrToN, a citizen of the United States, and a resident of Ghatham, in the county of Barnstable and State of Massachusetts, have invented an Improvement in VVeft-Replenishing Mechanism, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My invention relates to weft replenishing looms in which there are shifting shuttle boxes for a plurality of shuttles at one end of the loom, and a single shuttle box and a stationary magazine at the other end of the loom, said magazine having a plurality of guide-ways or compartments for supperposed bobbins or filling carriers of different color or character of filling, corresponding to the color or character of the filling in the different shuttles.

The object of this invention is to provide means to supply a fresh filling carrier, of an indicated color or character, to the running shuttle in a shifting shuttle box loom, and means to cause the filling of proper color or character to be in position to be supplied to the running shuttle, containing the exhausted carrier, in a loom which has no transferrer, whether or' not a change of a previous color or character has been effected. To accomplish this operation I have arranged the magazine in a manner to cause the filling carrier in the transferring position to be automatically disposed of should the transferring of said filling carrier into the running shuttle fail, owing to the improper boxing of the shuttle.

The stationary magazine, above referred to, is in this instance of the type shown and described in United States Letters Patent, No. 1,022,109 and in my present improve ments I combine this stationary magazine with mechanisms on the loom for raising the single shuttle box, which carries the active shuttle, to receive the new bobbin direct from the conveye'r of the stationary magazine, without using the transferrer arm ordinarily employed. The mechanisms referred to for raising the shuttle box on the plain end of the lay, are in this instance of the type shown and described in U. S. Letters Patent, No. 935,645.

In the operation of the loom, when a change of filling is indicated, on the practical or substantial exhaustion of filling in the active shuttle, the bobbin, which has the same color or character of filling thereon as the bobbin in the active shuttle, will be dropped from a compartment of the stationary magazine into the conveyor, and on the further movement of the releasing mechanism, the conveyor, with the released or dropped bobbin, will be moved to the center of the magazine and into a position above the shuttle box, when the lay has been moved to its front position. At the same time a lever on the stationary magazine is raised, and through intermediate connections, operates a sliding or starting tooth on a mutilated pinion, to move said sliding tooth into mesh with a mutilated gear on the bottom shaft of the loom, which causes said mutilated pinion to be revolved, and through an eccentric thereon, operate an angle lever, which is adapted to raise the single shuttle box on the lay, with the shuttle and the exhausted bobbin in the shuttle. The lower portion of the conveyor enters the active shuttle, and delivers a new bobbin to the same. r

The raising and lowering of-the single shuttle box on the lay is so timed, that its full operation will be accomplished in less than half the stroke of the lay.

My invention consists in certain novel features of construction of my improvements, above referred to, as will be hereinafter fully described.

I have shown in the drawings a detached portion of a stationary magazine of the type above'referred to, with a shuttle box raising mechanism of the type above referred to, combined therewith, sufiicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :-Figure 1 is an end view of a loom frame, carrying a stationary magazine of the type above referred to, with the shuttle box operating mechanism supported thereon, looking in the direction of arrow at, Fig. 2. Some of the parts are shown-in section. Fig. 2 is a front view. of the end of the loom, shown in Fig. 1, looking in the direction of arrow 7), same figure. Some of the parts are shown in section. Fig. 3 is an inner end view of the stationary magazine, looking in the direction of arrow 0, Fig. 2. Some of the parts are shown in section. Fig. 4 shows, on an enlarged scale, a sectional View of the butt end of the shuttle shown in Fig. 2, and the lower end of the conveyer arm, and the lower central portion of the magazine. Fig. 5 is a section, on line 5, Fig. 4, looking in the direction of arrow (Z, same figure, and Fig. 6 is a plan view of the shuttle shown in Fig. 4, looking in the direction of arrow 6, same figure.

In the accompanying drawings, 11 is the loom side or end frame, 12 is the breast beam, 13 the lay, 14 the lay sword, pivotally mounted at its lower end at 15, see Fig. 1; 16 is the connector from the lay sword to the crank shaft 17, 18 is the bottom shaft of the loom, see Fig. 1.

, 19 is a stand secured to the breast beam 12 and loom side 11, which is rigidly connected there to the inner end 20 of the stationary magazine, which has in this instance six vertically extending compartments or guide- ,Ways, 20, seexFig. 2, for the heads or butts 21 of the bobbins or filling carriers 21.

Carried on the transverse rods 22 is the outer end 23 of the stationary magazine, with'six vertically extending compartments for the tips of the bobbins 21. Each compartment or guide-way'is provided at its lower end with mechanisms for supporting the sets of bobbins therein, and also for re leasing the lowest bobbin in each set, preparatory to being conveyed tothe discharging center of the magazine, to be transferred into the actlve shuttle. The holding and releasing means consists in this instance of .sliding bars or blades 24, see Fig. 3, which are guided at each end thereof, and which blades, through the sliding movement communicated thereto,'move' from underneath the bobbins to release'and drop the bobbins in the usual way.

On the inner side of'the inner-end 20 of the magazine, are six vertically moving bars 25,: see Fig. 2, one for each compartment. These bars are loosely supported in guides 20, and have an up and down movement therein. The bars 25 are provided at their upper ends with weighted hooks 26, which are adapted, on their downwardmovement, toengage and rock the lever 27, which has its hub 27, secured on the rock shaft 28. Bearings. 20", see Fig. 3, on the magazine, have loosely mounted therein a longitudinally moving-rod 29. A slidingmotion is communicated to the rod 29, through angle lever'30, seeFig. 1, which, through a connector 31, and chain or cord 32 from the shift ing shuttle boxes on the opposite end of the loom, not shown, receives a reciprocating movement, to cause the rod 29 to move longitudinally into six different positions, according to the position of the shifting shuttle boxes. The longitudinally moving rod 29 has secured thereon, to move therewith, the hub 33, see Fig. 2, of an operator finger 33, to which is communicater'l a rocking motion through a lever 34, see fig. from the replenishing means, and intermediate connections thereto, not shown.

The rocking movement of the lever 34 will, through its engagement with the extension 25 on the vertically moving bar 25, move up or down a selected bar 25, and through the connection of each bar to the sliding blades 24, release and-allow a bobbin 21 to drop from its compartment.

The operating lever 30, see Fig. 1, has an arm 35 rigidly connected thereto, which is adapted to loosely receive a sliding block 36, see Fig. 3, which in its normal position rests upon a pin 37 at the lower end of the arm 35. The block 36 carries a stud 38, which has pivotally connected thereto one end of the rod or connector 39; the other end of the connector 39 has pivotally connected thereto a stud 40, which is fast on the end of a downwardly extending arm 41, which has its hub 41 loosely mounted, in this instance on a transverse shaft 42, which is journalecl in suitable hearings on the inner end 20 and-outer end 23 of the magazine. Also loosely mounted on the shaft 42 is the hub 43 of an arm 43, which extends toward the rear of the magazine, and has its end, when in its lower position, coincide with the axis or fulcrum of the arm 35. A stud 44 on the end of the arm 43, has pivotally connected thereto the upper end of the COHHGQ- tor 45; the lower end of said connector 45 is connected to the stud 38 on the sliding block 36, see Fig. 3. A belt or screw 46, on the arm 43, has loosely pivoted thereon the lower end of an upwardly extending latch 47. The upper end of the latch 47 has a pin 48 extending outwardly therefrom, and is adapted to be engaged by the'arm 27 on the lever 27, see Fig. 2, to move upwardly the arm 43, as shown.

A stud 49 on the arm 43 has pivotally connected thereto the. upper end of a vertically extending connector 50;. the lower end of said connector 50 is pivotally connected to a stud 51 on a lever 52, which has its hub 52 loosely mounted on a stud 53 on a stand 54. Extending rearwardly from the hub 52 is an arm 55 which has the engaging end 55, adapted to be engaged by the lay on itsbackward motion, to re-set and move downwardly the arm 43 to its inoperative position. I

The arm or conveyer 56 is made in this instance of the shape shown in Figs. 2 and otal ly connected to the end of a lever 64c coiled expansion spring 57 acts to yieldingly hold the conveyor arm 56 in engagement with the swinging arm 41, to move .therewith when the arm 41 is operated as above described. The lower end of the conveyer arm 56 has the enlarged portion 56", see Fig. 4, which is adapted to enter the shuttle 57 between the holding jaws 58, see Fig. 6, for the head 21" ofthe bobbin 21.

Extending lips 56 on the end 56, are provided to hold the head 21 of the bobbin 21, which is released from the magazine. A spring blade 59 is adapted to reach under the head of the bobbin, see Fig. i, which spring yieldingly moves outwardly when a new bobbin is transferred into the shuttle, and the shuttle box moved downwardly.

The magazine end 20 is provided with an extension 20, see Fig. 4, at its central portion, to force the head of the bobbin 11 into the shuttle when it is raised, as will be hereinafter described.

The transverse shaft 42 has secured thereon, on its opposite end at the outer end frame 23 of the magazine, the hub 60, see Fig. 2, of a downwardly extending arm 60, which arm is adapted to carry at its lower end 60", the tip of the released bobbin, see Figs. 1 and 2. Spring blades 61 are pro 'vided, which yieldinglyhold the tip of the bobbin 21 in position.

I will now describe the mechanisms for raising the shuttle box which carries the shuttle, to receive a new bobbin from the conveyor, which mechanisms are similar to those shown. and described in Letters Patent No. 9335;645, above referred to. .The

rock shaft 28 on the magazine carries in this connected thereto the upper end of a "downwardly extending connector rod 63; the lower end of said connector rod 63 is piv- 3 see Fig. 2, which has its hub 64 fast on a short shaft 65, which short shaft has a hearing 66 on a stand '66 secured to the loom frame. Also fast on the shaft is th-ehub 67 of the lever 67. The end of said lever 67 carries a pin 68, to which is pivotally connected one end 'of a horizontally extendshaft '18, to cause the rotation of a m-uti-' 'lated pinion 75; Themutilat-ed "pinion- 7-5 is loosely mounted on a stud 76 and is connected with aneccentric 77, to turn said eccentric. Also connected with the pinion 75 is a disk 78, having a recessed portion 78 on its periphery, into which is adapted to extend the two rounded portions 79, in this instance on one end of the lever 79, see Fig. 1. The hub 79 of the lever 79 is pivotally mounted 011 a stud 80 on the loom frame 11.

A helically coiled contraction spring 81 is attached at one end to the lever 79, and at its other end to a stud 81 on the frame 11, and acts to yieldingly hold the rounded portions 79 toward the disk 78, to cause them to enter the recessed portions 78 of said disk 78, to lock the disk 77 in its inoperative position after it has made one full turn.

The eccentric 77 has an arm 77 thereon, which is pivotally connected with one arm of a lever 82, which has its hub 82 loosely mounted on a stud 83 on the frame 11. The other arm 82 of the lever 82 is pivotally connected with a give-away device 84:, which consists of two clamp arms, which are yieldingly held in engagement by a contraction spring 85, with a stud 86 on the arm 82 of the lever 82. The clamp arms 84 are piv 'otally mounted at their lower ends on a stud 87, secured to the lower end of the box lifter rod 88. The box liftenrod 88 has a bearingv 'box or cell 91, to contain the active shuttle 57. The shuttle box 91 has a vertical movement, and is provided with projections which extend into guide-ways in the ends of the chuttlefbox guide frame '92, see Fig. 2.

By the raising of the shuttle box 82, the

conveyer arms 56 and 60 enter the shuttle 57, and a new bobbin is inserted from the conveyer arms, and the spent bobbin 21 will pass through an opening in the shuttle in the usual way.

In my iimn'ovements I have provided a plunger a which is slidably mounted within the magazine end 20, said plunger (4 having pivota lly secured thereto, at its upper end, one end of a lever 5, said lever 7; being loosely mounted on astud a secured in the upper portion 54 of the stand 54. The opposite end of said lever b has pivotal-ly secured thereto the upper end of a rod (Z, said rod (Z being loosely guided in a bearing a of a stand 6 secured to the loomsi-de 11. The lower end of said rod (Z has pivotally securedthereto a cam roll 7 which is engaged by the periphery of a cam 9 secured on the crank shaft 17. Said cam roll f is retained in engagement with the cam gby means ofith'e compression spring h encircling said rod d and bearing at one end against the bearing 6, the opposite end of said spring having its bearing against the enlarged portion d of said rod (Z.

. The cam g-is so timed that should the transference of the bobbin from the con- I veyer to the shuttle fail, the plunger (4 Will stantial exhaustion of filling in the active shuttle.
